“…In the course of the years, other workers have described the method, some with more and some with less detail (Apolczyn,6;Beck,12;Bratt,47;Piotrowski,' 234;190;Hertz,114,115,116,128;Klopfer,165,166,167;Hunter,137;Dubitscher,69,70,71;Lopfe,192;MacCalman,193;Mandowsky,197;Rizzo,247;Monnier,207;Salas,257;Soukup,281;Schneider,268;Vernon,298). Three manuals have appeared in recent years, in French by Loosli-Usteri (161,191), in German by Schneider (269), and in English by Beck (21). Beck's manual, the first book to be published in English, marks an important step forward, since it is the first to emphasize the objective-standardized approach to the method and call a halt to the exclusive reliance on personal norms and subjective estimate.…”
